Chaotic maps based on binary particle swarm optimization for feature selection
TL;DR: Chaos binary particle swarm optimization (CBPSO) is proposed to implement the feature selection, in which the K-nearest neighbor (K-NN) method with leave-one-out cross-validation (LOOCV) serves as a classifier for evaluating classification accuracies.

Fundamentals of synchronization in chaotic systems, concepts, and applications.
TL;DR: Results from various areas of chaotic synchronization are collected in a review article format with a tutorial emphasis, with particular focus on the recent notion of synchronous substitution-a method to synchronize chaotic systems using a larger class of scalar chaotic coupling signals than previously thought possible.
